The Hot Rolling Process
There are some fundamental differences between hot rolled and cold rolled steel. The differences are related to the methods of processing and are not relevant to the specification of the metal or the grade.
The Hot Rolled steel
In the hot rolling process, the steel is rolled at a temperature higher than the recrystallization point, typically higher than 1700° F. When heated to such high temperatures, steel can be manipulated easily. The hot rolling process can produce great amounts of steel without the delays of cooling and reheating.
However, when hot rolled steel cools the final side is less predictable…Continue Reading
